Samsung Galaxy A21s test / review

Samsung Galaxy A21s test / review (diepgaande beoordeling, geen biais)
Categorie: Tests en beoordelingen

After testing several Chinese brands, I decided to make a come back to Samsung by buying the Samsung Galaxy A21s. What motivated me to buy this phone is mainly the price because it falls into the same price category as the latest models from Xiaomi that I tested.[b][b]Samsung has always been more expensive than Xiaomi and the price/performance ratio was always in favor of Xiaomi. I wanted to see if things had changed.[b][b]The Samsung Galaxy A21s is priced on par with the Redmi Note 9s but seems to be more in competition with the Redmi Note 9. [b][b]My test will show whether the price difference is justified and how the Samsung Galaxy A21s can compete with its Chinese competitor.[b][b][b][b][b]

Structure of my tests

I test the phones according to a pre-established structure (see below) to provide you with as much information as possible. Unfortunately, this takes a long time. Some tests like network performance tests take several days and for photo tests I sometimes have to wait until the weather is suitable to take pictures in good conditions. I am therefore obliged to publish the tests step by step, so I invite you to come back if the test is not complete at the time of your visit.[b] [device_intro device="smartphone" lg="en"]

July 2020: purchase of the Samsung Galaxy A21s on RueDuCommerce with trade-in pack[b]01/08/2020: I start the test with a little delay because I had a lot of other devices to test.[b][b]

Why this phone?

As I wrote above, it was the price that motivated me to buy this phone and it will probably be the case for many buyers as well. If you are not ready to buy a Chinese brand yet, this Samsung will surely be one of the first choices for buyers who don't want to pay more than 200€ for their phone.[b][b]Beside the price I also look at other elements that show that in theory this Samsung can't compete with the Redmi Note 9s but the test should be able to show if this is really the case. It is clearly a match between the Samsung entry-level versus the Xiaomi entry-level.[b][b]

[b]The Samsung Galaxy A21s comes in a classic white box containing the phone, charger, USB cable, earphones and manual.[b][b]In the same price range, Xiaomi offers in addition a transparent protection but does not offer earphones. Those who want to protect their smartphone against scratches will therefore have to buy an extra protection.[b][b][b][b][b][b]

First configuration

The configuration of the Samsung has changed in recent months and this is not a good thing. Samsung now requires the use of an application called Smart Switch to transfer data from the old phone to the new one. So you still need to have the old phone to install the application. I find this kind of process completely useless and superfluous. Android is linked to a Google account and this Google account allows you to transfer and synchronize data across multiple devices. Smart Switch is an attempt by Samsung to access this data which is usually only accessible through the Google account.[b][b]At the end of the startup procedure, the phone will propose a screen to create a Samsung account, it's a fairly common practice but even refusing, Samsung will try to force the installation of some applications two screens later.[b][b]The Samsung Galaxy A21s has only 32Gb of data, it's been a long time since I've had a phone with so little storage memory. So I had to make a choice in what I wanted to copy from my old phone which had 64 Gb because the storage capacity of the Samsung did not allow me to transfer everything.[b][b][b][b]

[b]The Samsung Galaxy A21s is an entry-level phone but the finishes are correct, the backside sags a bit when you press it but Samsung is used to making phones with a good level of finish in all price ranges. In this price range, it is possible to find phones with a glass back that offer a better finish but this doesn't change anything to the use of the phone, it's a rather subjective choice.[b][b]

[b][b]The lower part of the phone has a very classic configuration with a USB type C port, a mono speaker and a jack socket for the headset.[b][b]

[b][b]The volume and start buttons are located on the right side of the phone, the position of these buttons is similar to what is found on most phones today. The buttons are made of plastic, they don't stick out very strongly from the device but they are separated by enough space to be able to distinguish them. The SIM drawer is on the left side.[b][b]

[b][b]The back of the phone is almost perfectly smooth, it is only interrupted by the photo module which does not stick out much. Xiaomi tends to use photo modules that come out of the phone quite strongly, Samsung is better off.[b][b]

[b][b]The Samsung Galaxy A21s has a large 6.5-inch screen and an occupancy rate of 82%, a border is visible all around the screen with a slightly thicker border at the bottom of the screen. The A21s is quite similar to what I was able to test at Xiaomi both in screen size and screen occupancy percentage. These borders are not annoying and the screen size offers a comfortable experience.[b][b]The camera for the selfies is housed in the top left of the screen, it appears as a black dot on the screen but it never bothered me in the use of the phone, the black dot is quite discreet.[b][b]


[b]The information below comes from the Device Info HW application. The application provides detailed technical information about the tested phone.I bought the 3Gb version with 32 Gb of storage. There is another version with 4Gb and 64 Gb of storage.[b][b]I don't advise to buy a 32Gb version because even if you don't use a lot of applications, the lack of space will quickly force you to clean the phone.[b][b][b][b][b]

CPU / GPU Performance

CPU : Samsung ExyNeens 850
GPU : ARM Mali G-76 1Ghz
Geheugen (RAM) : 3 - 4 Gb
Opslagcapaciteit : 32 - 64Gb
[b][b]The Samsung Galaxy A21s is equipped with an Exynos 850 processor, it is an entry-level processor that offers lower performance than the Snapdragon 665. The processor is clearly not the strength of this phone and this is also felt in use. My opinion is obviously a bit biased because I'm used to testing more powerful phones and the difference is obvious. If on the other hand you have always bought entry-level phones, you probably won't feel this lack of reactivity as much. Of course, this does not prevent you from using the phone, it is first of all a question of comfort.[b][b]

Benchmark Antutu/3DMark

As I wrote above, the Samsung Galaxy A21s is not a performance brute and even if you are not a gamer, this lack of performance is felt when using the phone at every screen change or application launch. [b][b]I got a score of 123,000 points on Antutu, this is one of the lowest scores I've gotten so far. In this price range there, Samsung's positioning is therefore not very good. With a price of 199€, it's possible to buy a Redmi Note 9s which scores 270 000 points on Antutu. So the price/performance ratio is really not good at Samsung.[b][b][b][b]

[b]Gaming[b]To test the performance in game, I download the mobile PUBG game and evaluate the in-game experience, graphics level and depth of vision. This game is quite demanding and should help you evaluating the performance of a phone.[b][b]The Samsung Galaxy A21s is not a phone for gamers but it allows you to run PUBG Mobile with a few sacrifices. The game works but the animations are jerky and the fluidity of the game is not always optimal. The screen resolution of the A21s is lower than average which allows the games to require less processing but this is at the price of a slightly degraded visual experience.[b][b]

Signal 4G (before december 2020)[b]The ability to pick up the network correctly is an essential element for a phone but it is only very rarely measured. To measure a phone's ability to pick up the network, I perform a large number of measurements on the same cells to be able to compare phones under similar conditions. The signal is measured in dBm, a value of -90dBm indicates a worse signal than -70dBm. These measurements are therefore taken under real conditions and not in a laboratory, they are not scientific but give a good indication of performance.

[b]Out of 1000 measurements I got an average signal of -97.78 dBm with the Samsung Galaxy A21s where I got -99.4 dBm with a Redmi Note 9s under the same conditions. The Samsung Galaxy A21s picks up the network better than the Redmi, this is not a surprise as it is a weak point of the Redmi range.[b][b]The Samsung's score is a bit above average, it exceeds most of the Redmi I tested.[b][b][b]Signal 4G (from December 2020)[b]I decided to change the methodology for measuring the network because I noticed that the configuration of the mobile network changes over time. This makes it more difficult to compare phones because the conditions are no longer exactly the same.[b][b]To overcome this problem, I set up a device that captures 24 hours a day about ten parameters from the mobile network (ex: cell id, rssi, rsrq, snr, frequency,...). I then place the phone next to the device for 24 to 48 hours taking the same measurements so that I can compare them. [b][b] Overview of the phones tested with this methodology[b][b]

Let op: de theoretische maximale snelheid van een telefoon wordt vaak beperkt door de configuratie van het mobiele netwerk en de congestie van het netwerk op het moment van de meting. Dus misschien kun je een hogere snelheid halen op een ander netwerk
[b]I got a 4G download speed of 147 Mbps which puts the A21s in the good average of the phones I tested. The network is probably limited to 150 Mbps but this Galaxy A21s will allow you to stream in HD without any problem.[b][b][b]

Wifi performance

To test a phone's ability to receive the network properly, I take measurements near my router and then remotely (and always at the same place). This gives me an average in dBm where a value of -90 dBm indicates poorer performance than a value at -30 dBm.[b]

Opmerking: ik heb een 400 Mbps-lijn en een modem die hogere snelheden kan leveren, maar ik weet nooit zeker hoeveel bandbreedte er beschikbaar is als ik een test doe.

GPS performance

[b]To test the quality of the GPS signal I use the Offline Maps application and I make the same train trip in pedestrian mode. Why? In pedestrian mode, the GPS does not artificially correct the signal to stick to the road, it has no markings, so you can see the actual position. I then use an application to measure the accuracy of the signal. [b][b]The Samsung Galaxy A21s captures most common GPS networks (GPS,Galileo,Baidou,...). I obtained an accuracy at 4 meters which fluctuate regularly between 4 and 6 meters. This is clearly not the best score I got and the lack of power of the phone may also create a discrepancy between the actual position and the displayed position.

Opmerking: een nauwkeurigheid van 3 meter of minder kan eenvoudig worden gecorrigeerd door een goede GPS-applicatie. De telefoonprestaties spelen ook een rol bij de snelheid waarmee je scherm wordt bijgewerkt, dus de nauwkeurigheid kan in het gedrang komen door een te trage weergave.

Vanaf maart 2020 heb ik mijn subjectieve batterijtest vervangen door een technische test om het werkelijke gedrag van de batterij beter te kunnen meten. Nu test ik de autonomie en de oplaadtijd onder absoluut identieke omstandigheden. Ik voer verschillende metingen uit, zodat deze test alleen al enkele dagen duurt en ik de telefoon voor niets anders kan gebruiken.

Batterijduur - methodologie
Om de levensduur van de batterij te testen, meet ik het batterijverbruik elke minuut in strikt identieke omstandigheden om telefoons te kunnen vergelijken en ook om je in staat te stellen je telefoon in dezelfde omstandigheden te evalueren. Ik sluit elke invloed uit van toepassingen die de meting zouden kunnen verstoren. De autonomie is niet lineair, de batterij ontlaadt zich soms veel sneller aan het einde. Dit is een frustrerend fenomeen, maar met mijn metingen weet je of je snel een oplader moet vinden.

De batterij van de Samsung Galaxy A21s heeft een capaciteit van 5000 mAh en is ontladen van 100% tot 1% in 729.00 minuten met 100% helderheid, hij is ontladen van 100% tot 1% in 1283.00 met 50% helderheid. Op deze manier krijg ik een gemiddelde ontlaadsnelheid van 0.14% per minuut bij 100% lichtsterkte en 0.08% per minuut bij 50% lichtsterkte, het verbruik is dus 6.86 mA per minuut bij 100% lichtsterkte en 3.90 bij 50% lichtsterkte. Om de efficiëntie van de telefoon en de invloed ervan op de batterij te kunnen vergelijken, moet je de 6.86 (of 50%) score vergelijken met die van andere smartphones, het cijfer moet zo laag mogelijk zijn.

Laadtijd - methodologie
Om de oplaadtijd te testen, gebruik ik altijd dezelfde lader met dezelfde kabel. Ik meet de oplaadtijd minuut voor minuut om de evolutie van de lading en de oplaadsnelheid te zien. De laadsnelheid van een batterij is niet lineair, maar vaak sneller aan het begin en langzamer aan het einde. De lader is compatibel met snel laden.

De accu van het Samsung Galaxy A21s heeft een capaciteit van 5000 mAh en is opgeladen van 1% tot 100% in 166.00 minuten. Dit geeft me een gemiddelde laadsnelheid van 0.60% per minuut en dus een toename van 30.12 mA per minuut. Om de prestaties van de Samsung Galaxy A21s te vergelijken met andere telefoons, moet je de 30.12 per minuut score gebruiken, deze score moet zo hoog mogelijk zijn.

In het bijzonder: de laadsnelheid is niet altijd lineair, de onderstaande grafiek geef je een indicatie van het gedrag van de batterij.

De volgende tabel geeft een overzicht van de geteste telefoons met de technische accutest, ze zijn gerangschikt in volgorde van efficiëntie. Een hogere batterijcapaciteit zou logischerwijs moeten resulteren in een hogere levensduur van de batterij, maar dat is niet altijd het geval en het geeft geen indicatie van de efficiëntie van een telefoon.

helpHoe lees je deze cijfers?
De batterijcapaciteit is een belangrijk element bij het bepalen van de autonomie van een telefoon, maar het is niet de enige factor. Een telefoon met een grote batterij kan een kortere batterijduur hebben als hij meer stroom verbruikt. Als ik een voorbeeld uit het dagelijks leven zou moeten nemen, zou ik het universum van de auto gebruiken. Als een auto een grote brandstoftank heeft, zou hij een langere afstand moeten kunnen rijden, tenzij het gemiddelde brandstofverbruik hoger is. De score voor de efficiëntie van de batterij werkt op dezelfde manier, hij moet zo laag mogelijk zijn en staat voor het energieverbruik van de telefoon. Deze verschillen in efficiëntie zijn vaak gerelateerd aan de helderheid van het scherm, grote heldere schermen hebben de neiging om meer energie te verbruiken en zelfs als ze een grote batterij hebben, zal hun bereik korter zijn.

samengevat [battery product="samsung-galaxy-a21s" capa="5000" lg="en"][b][b]The Samsung Galaxy A21s has a 5000 mAh battery that will give you a very comfortable autonomy of several days in normal use. [b][b]Charging the Samsung is quite fast, I recharged the battery from 1% to 100% in 166 minutes, it's about the same as the Redmi Note 9.[b][b]The battery capacity allows to last several days but the phone could have been more efficient because at equal capacity, other phones do much better. In particular, the Redmi Note 9 lasts 500 minutes longer with the display on at 50%.[b][b]

Photo camera test

To test the quality of photos produced by a phone, I do a technical test (resolution, sharpness, chromatic aberration,...) in studio (identical conditions) to evaluate the technical part objectively. From the second half of 2020, I built my own laboratory to take completely objective technical measurements. I then take pictures in real conditions to see how the camera performs. I then evaluate these photos according to my criteria but I publish the photos so that you can evaluate the result according to your criteria.[b]


Selfie / resolutie : 13
Resolutie : 48
Sensor : Samsung S5KGM2
Video resolutie : 1080p
mm wide angle : 4.6 mm
mm ultra wide angle : 1.42 mm
The Samsung Galaxy A21s is equipped with a 48 million pixel Samsung S5KGM2 main sensor which is also used in the Redmi Note 9, the Redmi Note 8 and the Samsung Galaxy A51. [b]This sensor has already proven itself on other phones, so it is the image processing provided by Samsung that can make the difference with other brands.[b][b]Default app[b]Samsung has made the choice of simplicity with its photo application. Where Xiaomi seems lost in a race for complexity, Samsung has chosen to limit the entry points to the bare minimum by placing the least used features behind a separate menu.[b][b]The photo application therefore offers by default an entry point for photo, video, portrait mode and everything else can be found in a sub-menu containing a pro mode, panorama mode, macro mode and food mode.[b][b]Since most users of this type of phone will be satisfied with the basic features, Samsung has probably made the right choice. Samsung also had the good idea to divert the icons to change the sensor, this makes them much more readable than with Xiaomi.[b][b][b]

The photo is properly exposed, the colors are natural even if they could have been a little brighter. The sharpness is good and the photo has no particular defects. I had not obtained such a good result with the Redmi Note 9 which applied an incorrect treatment on the colors.[b][b]Ultra wide angle sensor[b]

So it has the advantage of capturing very close subjects but the distortion is very important. Usually the distortion is mostly visible in the periphery but here we see that the Statue of Liberty is thinner, the figure on the right is abnormally curved, the rest of the picture follows my same tendency. The exposure time is not good either, the photo is globally too dark and this is quite often the case for wide angles when there was enough light to increase the exposure time without risking to make a blurry photo.[b][b]This first technical test is promising for the future, the main sensor produces a better result than other phones that use exactly the same sensor. Samsung has an undeniable know-how in photo processing.[b][b][b]Photo test / sunny[b]Main sensor[b]

Sharpness decreases as you move away from the center, it's quite visible on the foliage on the left. It is therefore always necessary to take care to have the main subject close to the center otherwise it may end up in a blurred area with significant distortion. I am positively surprised by the color treatment because it is very similar to what I obtained with the main sensor.[b][b]Main sensor[b]

The tops of the trees seem to have been over-treated because I can see a thin white net surrounding the leaves.[b][b]The following pictures confirm the findings made on these first pictures. I knew that this sensor was capable of producing good pictures because I had been able to test it in other phones, but Samsung managed to apply quality processing to the images which allows the Galaxy A21s to move up a notch above other phones using the same sensor.[b][b][b][b][b]Photo test / cloudy[b][b]Main sensor[b]

This sensor does not perform as well under these conditions, and in addition, always make sure to have the main subject in the center to avoid falling into the peripheral blur area.[b][b]Pictures in cloudy weather are not extraordinary but they are quite correct for this price range.

In the same price range, we find phones that are able to do much better using the same photo sensor.[b][b]Ultra wide angle sensor[b]

Video quality

Stabilisation[b][b][b]The Samsung Galaxy A21s does not have video stabilisation, vibrations and shocks will not be corrected. I haven't found a phone with good stabilization in this price range yet, so the Samsung is neither better nor worse than other phones in this price range.[b][b]Video normale conditions[b][b]The Samsung Galaxy A21s is capable of producing good videos when the light is good. Sharpness is good, colours are richly saturated and sound is well reproduced. The weakness of the Galaxy A21s is its lack of power and this is felt a little for videos because the recalculation of pixels during movements or changes in exposure is quite visible. The video processing is a bit too slow but this problem is only visible with important movements or brightness changes.[b][b]Video low light[b][b][b]The Samsung Galaxy A21s produces fairly average videos at night. The video should have been exposed a little more and the focus makes visible back and forth between the different elements of the video. When the scenery is too dark, it can't be fixed in one place. The digital noise is quite visible too.[b][b]In this price range, the Redmi Note 9s does better.[b][b]

Audio quality

To test the quality of the phone's audio output, I connect the device's audio output to a measuring tool, then play sounds on all frequencies and measure the differences between the original sound and the sound produced by the phone. In this way I measure the phone's ability to correctly reproduce all sounds.[b]
Frequency Respons : +0.03 / -0.08
Noise Level : -93.7
Dynamic Range : 93.2
THD : 3.205
Intermodulation : 1.765
Stereo crosstalk : -90.5
In this price range, you should not expect to find a phone with outstanding audio performance, most phones offer good sound without being exceptional.[b][b]The Samsung Galaxy a21s is no exception. The sound produced by the speaker is of average quality, the sound is not very powerful either. [b][b]With a headset the sound is of better quality and offers more power.[b][b]Frequency Response[b]This test is intended to test the device's ability to correctly reproduce all frequencies. The white line in the middle of the graph is the ideal situation and the other colors come from tests on different phones. A deviation from the reference line indicates a deviation from the ideal situation. To see good sound at all frequencies, it is therefore necessary to get as close as possible to the reference line.
[b]I compared the Samsung Galaxy a21s with the Redmi Note 9 to see which phone reproduced the frequencies more correctly. In the low frequencies it is the Redmi that is the most faithful and in the high frequencies it is the Samsung that is the most faithful. However, you have to be really careful to perceive the difference, it will also depend on the type of music. As a whole the A21s offers a good reproduction of frequencies but to find better it is necessary to pay more expensive.[b][b]Dynamic Range[b]This test is designed to test a phone's ability to play sounds at different volume levels. Here too, the phones must be as close as possible to the reference.
[b][b]The Galaxy A21s manages to produce a correct sound on all frequencies by offering much more power than the Redmi Note 9, this power is not very well controlled because at maximum volume the distortions are more important. So you have to lower the volume by 2 or 3 steps to get a better sound quality.[b][b]Noise Level[b]This test aims to identify if the device under test is able to reproduce sounds without too much noise. A high score indicates a low parasite rate, a lower score indicates a higher presence of parasites.
[b][b]The Galaxy A21s is capable of reproducing sound without interference, and it does much better than the Redmi Note 9 even if it is difficult to perceive the difference to the ear.[b][b]

Screen quality

To test the screen, I use a colorimetric probe that measures the color accuracy of a screen, as well as other parameters to see if a screen is able to correctly reproduce an image. I also test the brightness level to determine if the screen will be able to display an image in full sunlight.[b]

[b][b]Samsung generally produces good displays but this rule does not seem to apply to entry-level models. The Galaxy A21s has a color difference dE of 7.2, which is quite far from what I can get with a Redmi Note 9s for the same price. What does this mean? If you compare the screen of the Samsung with a screen like the one of the Redmi Note 9s, you will see a visible color difference. The Galaxy A21s deviates from the standard especially in the green area.[b][b]The screen is quite large but is limited to a resolution of 720x1600 where we usually find a resolution of 1080x2400 pixels on other phones of the same price. Using fewer pixels on the same surface means a less detailed image. [b][b][b]Top 10 - rangschikking van de beste schermen op basis van colorimetrie

Let op: het colorimetrische verschil wordt gemeten in dE. Na drie uur zal het menselijk oog een colorimetrisch verschil waarnemen, dus de dE moet het laagst zijn. De tests zijn allemaal uitgevoerd met een colorimetrische sonde.
[b]Brightness / Contrast[b]I measured a brightness of 440 cd/m², this is a good score that should allow you to use this phone in almost any condition but there are many phones today that can produce much more light. This can be felt in bright sunlight where 440 cd/m² may be slightly insufficient for good readability.[b][b] I measured a contrast ratio of 1350:1, which is an average score for this type of screen. Once again the Redmi Note 9s does better for the same price.[b][b]


The Samsung Galaxy A21s is equipped with a fingerprint sensor on the back, this sensor is fast and efficient. It also works better than most on-screen sensors. The 2D facial recognition also works well.[b][b]

Operating system

The Samsung Galaxy A21s benefits from Samsung's know-how for its operating system. Samsung UI is undoubtedly one of the most advanced operating systems on the market. If you come from a basic Android version, the adaptation time will be minimal.[b][b][b]

Compare Samsung Galaxy A21s with the others

Ik heb voor elke test een score van 1 tot 10 toegekend die de sterke en zwakke punten van een product bepaalt. Ik gebruik 0 voor criteria die (nog) niet zijn getest. Een score van 1 tot 3 duidt op slechte prestaties (en ja, dat is ook zo), een score van 4 tot 6 duidt op gemiddelde prestaties, een score van 7 tot 8 duidt op goede prestaties en een score van 9 en 10 duidt op uitzonderlijke prestaties. .
De score wordt berekend op basis van mijn metingen en als er geen metingen zijn, is het een subjectieve mening op basis van mijn ervaring.

De scores zijn niet statisch, ze veranderen in de loop van de tijd omdat de prestaties van nieuwe producten veranderen en hiermee moet rekening worden gehouden.
